1 Samuel 23:26-27

And Saul went on this side of the mountain, and David and his men on that side of the mountain: and David made haste to get away for fear of Saul; for Saul and his men compassed David and his men round about to take them. But there came a messenger unto Saul, saying, Haste thee, and come; for the Philistines have made a raid upon the land.
